BACKGROUND

Technical Field

The present disclosure relates to an imaging lens module. Moreparticularly, the present disclosure relates to an imaging lens moduleapplicable to mobile terminals.

Description of Related Art

For the conventional optical lens modules used in the mobile terminals,the appearance of the lens element is mostly disc-shaped, and theappearance of the optical component is mostly annular or cylindrical forthe advantages of manufacturing. When the pixels of the optical lensmodule are increased, the volume and the outer diameter of the lenselement and the optical component should be enlarged, and it results inproblems of non-imaging light and poor image quality. Hence, thetechnique of volume shrinkage for the optical lens modules is developed.

The conventional way to shrink the volume of the optical lens modules iscutting the outer diameters of the lens elements and the opticalcomponents, however, the assembly strength between the lens elements andthe optical components would be decreased. Moreover, the optical qualityand manufacturing yield rate would also be reduced. For the optical lensmodules with greater outer diameter, the excessive stray light cannot beeffectively suppressed.

Therefore, the optical lens modules with properties of volume shrinkage,stray light effectively suppressed and stable quality are urgentlyrequired to the markets.
